8. How to Save Settings for Matching the Step Recall Setting the instrument to step recall mode allows the saved settings to be recalled in order by first pressing the RECALL button and then pressing the ENTER button repeatedly In this mode the instrument loops from number 0 to the number set with the LAST RECALL STEP item Refer to RECALL Button on page 3 30 for details on the step recall mode Remember the following points when saving settings m Store the desired settings in recall order starting with memory number 0 m A given memory will hold the initial settings even if the settings are not explicitly stored Initial Settings on page E 2 for details m The last memory to be recalled in step recall is specified with the LAST RECALL STEP item in the system menu RECALL Button This button recalls settings saved with the SAVE button or the initial settings saved as the default and sets up the instrument There are two recall techniques normal recall in which a specified memory number is recalled and step recall in which the memory number is changed automatically in sequence When shipped from the factory or SECURE Executing Factory Reset all the setting memories nonvolatile memory numbers 0 to 19 hold the initial settings See Secure Settings Factory Settings on page E 4 for details The features of these modes are described below Normal Recall Mode In this mode the user specifies the memory number to recall sto
